Question 1
A transformer steps up voltage from 11 kV to 400 kV. If the input current is 500 A, calculate the output current assuming ideal conditions.
💡 Hint: Remember the relationship between voltage and current is inversely proportional in transformers.
Question 2
Discuss the impacts of core losses on the performance of large-scale power transmission.
💡 Hint: Consider how even idle transformers still consume energy through core losses.
